MSI X570 chipset support
Hey,
I recently got an MSI X570 Gaming Edge Wifi and stumbled upon this project to see if I could control the RGB values with it. Unfortunately it doesn't seem to work, but I'm not getting an error message either.
Has the byte layout changed? A different chip maybe? Anything I can do to assist, let me know.
Same observed behavior with the X570 Gaming Plus. Also interested and happy to help.
Can someone figure out the superio chip used on these boards? That may help get closer to controlling them.
Update: From what I have read, all Msi X570 boards use the Nuvoton Nct6797 super io chip. You might have to do a little reverse engineering to find the data bits you have to write to this newer chip, then fork this project or make a PR with the new data bits being used.
Second Update: it is actually a NCT6797D. I don’t know if the D makes a difference
The Nct6795D seems to be used on a lot of msi X470 and 370 motherboards.

Looks like X570 may be using a USB chip:

I started digging through the pcap files that Jeffery posted for me on my OpenRGB Gitlab. I've documented my initial findings in this comment:

It's definitely a USB HID device and the RGB pattern is pretty clear here. We may need more pcaps to truly understand the protocol. I'll write up a wiki page on my project's wiki to document the protocol.
Unfortunately I don't have one of these boards to develop on, but I've done USB drivers for other stuff and this doesn't look too difficult to reproduce.
The PR on OpenRPG has been merged, so that should help! https://gitlab.com/CalcProgrammer1/OpenRGB/-/merge_requests/21
